Subject: remote debugging with m68k-stub

I'm trying to debug some program with the help of 
the m68k stub file. 
When I start the program in the remote target 
(motorola 68000) the connexion with gdb 
(in the host machine Sparc Sun Solaris) seems 
to be a succes:
	
	(gdb) target remote mark:5000
	Remote debugging using mark:5000
	0x00840007 in ?? ()
	(gdb) bt
	#0  0x00381118 in ?? ()
	#1  0x00010156 in ?? ()
	(gdb)

PS: 0x00840007 and 0x00381118 not corresponding
    to a correct memory acces.
A lot of data packet is send throw the serial link.


After that, I try to continue the program execution
with the continue gdb command: 	

	(gdb) c
	Continuing.
	Can't send signals to this remote system.  
	SIGEMT not sent.
	Program received signal SIGEMT, Emulation trap.
	0x00381118 in ?? ()

In the main function beginning I call the set_debug_traps
function to initialise exceptions address. After, I call
the Breakpoint function (TRAP #1) to connect with gdb.
During the execution the program never return of the
TRAP #1 exception (it stay in the handle_exception function).

I thing the problem can be a bad address reference.

What can I do to resume the program execution ??
If somebody has any idea, thanks to thing to me :-) 

Thanks
